DOOR-CHECK.

Speceation of Letters Patent.

Patented March 12, 1907.

Application filed December 19, 1906. Serial No. 348.583.

Be it known that I, MARVIN L. HARRIS, a citizen of the United States,and a resident of Newport News, in the county of Warwick and State ofVirginia, have invented certain i new and useful Improvements in Door-Checks, of which the following is a full and clear specification,reference being had to the accompanying drawing, in which- Figure l is aperspective view of the lower end of an open door, showing my deviceapplied thereto in a locked position; Fig. 2, a vertical longitudinalsection of the device,

showing the locking-legs dotted in position for engagement with thefloor, said section being taken on the line 2 2 of Fig. 3; and Fig. g

3, a transverse section on the line 3 3 of Fig. 2.

The object of this invention is to provide a f simple door-holdingdevice which will hold the door in any position desired against,`

movement in either direction and which may be actuated by means of apair of foot-operated pins or rods, as more fully hereinafter set forth.

Referring to the drawing annexed by reference characters, A designates ahollow supporting bar or casing, which is provided at one end with avertical lange a, which adapts it to be attached to a door in the mannershown in Fig. l. pivoted upon horizontal transverse pins c, and theselegs depend from the casing in a diverging manner, one inclining towardthe door and the other away from the door. On the bottom of each leg isa cup c2, in which is a rubber or other resilient floor-engaging pad R.

A pair of toggle-links D are mounted between the legs and are adapted tobreak upward, their inner ends being pivoted together at d and theirouter ends by pivots d/ to inward-extending ears c on the legs.Connected to the knuckle d is a vertical push-rod B, which works upthrough a hole in the top of the casing or support and is normallyraised by means of a coil-spring S. In the side of the rod B is a notchb, having its lower shoulder square and its upper shoulder A pair oflegs or arms C are i casing and being normally held up bya coill springS. The pivot g is mounted on and moves vertically with the rod E, and inorder l to swing the lower end of rod E forwardly when it is pusheddown, and thus withdraw l catch F from notch b, as shownin dotted llines in Fig. 2, the said movable pivot g is i pivotally connected to astationary pivot y i by means of a horizontal link G, extending towardthe outer end of the support. A resilient buffer R is mounted in the endof the casing or support to prevent the end of the casing and thedoor-knob from striking the i i i wall or the wainscoting or thewashboard back of the door.

It will be observed that when the push-rod l B is released it isnormally raised by its spring, and the locking feet or legs are thus g'swung downwardly and toward each other, The device is so positioned onthe door that l these locking-feet strike the Hoor before they arebrought to a vertical position,l as shown in Fig. 2, in which positionthey lock the door against movement in either direction. The bottomfaces of the pads R are so angularly disposed with reference to the feetthat When the device is in locking position they abut 1 squarely againstthe lloor or the carpet, thus preventing injury to the floor or carpetby scraping or biting into the iioor or carpet.

To unlock the device, it is simply necessary ,l to press down on the rodB, which straightens out the toggle and lifts the feet olf the Hoor. Assoon as the rod B has descended far enough the latch F springs intonotch b, and thus prevents the rod returning to its l normal position,thus holding the lockingl feet olf the door.

To lock the device, it is simply necessary to press down on rod E untillatch F releases rod B, as stated.

,` It will be observed that the push-rods may be conveniently actuatedby thefoot of the l operator.

Having thus fully described my invention, i what I claim, and desire tosecure by Letters l Patent, isl. In combination with a support adaptedfor attachment to a door, a pair of lockingfeet pivotally depending fromsaid support and inclining away from each other and nor- ,I inallytending to swing downward toward each other into engagement with thefloor, j foot-operated means between the arms for l spreading andraising them against their norl mal tendency, and foot-operated meansfor IOO IlO

arms or vfeet pivotally depending from said normally locking the arms intheir raised position.

2. In combination With a support adapted 'for attachment to a door, apair of locking 3. In combination With a support adapted 1 forattachment to a door, a pair of floor-em i gaging legs depending fromsaid support and inclining away Jfrom each other, a pair of toggle-linksconnected to the legs and to each other, a push-rod and a spring fornormally raising it, said push-rod being provided with a locking-notchand being pivotally connected to the knuckle of the toggle, and alatching device for said puslkrod embodying a second push-rod and meansfor normally holding it up.

In testimony whereof I hereunto affix my signature in the presence oftwo Witnesses, this 18th day of December, 1906.

MARVIN L. HARRIS.
